This application claims priority from U.S. Provisional Patent Application Ser. No. 60/631,337, filed Nov. 29, 2004, entitled Fixed-line Missed Call Alert. The entirety of that provisional application is incorporated herein by reference.
The present invention relates to providing a Missed Call Alert (MCA). More specifically, the present invention relates to providing an MCA for a call missed by a device in one telecommunication network to a device in a different telecommunication network.
Many solutions to provide Missed Call Alerts (MCAs) to wireless phones are known in the art. These solutions share a common approach. Namely, when a network element determines that a call terminating at a mobile phone is “missed”, the caller identification (caller ID) of the caller is sent to a Short Message Service Center (SMSC). The SMSC delivers an MCA as an SMS alert to that mobile subscriber's handset. “Missed” means that either the mobile subscriber handset is off or the mobile subscriber handset is busy, not answering or out of coverage. There may be further qualifications to a “missed” call, for example—a call attempt may qualify as “missed” only if the caller has not left a voicemail to the called mobile subscriber.
If the caller is also a mobile subscriber, there are also solutions that alert the caller via SMS if the original called party is available (in coverage, not busy, or powered on) again. The mobile caller can be restricted to the same mobile network or may be calling from any other mobile or fixed-line network depending on whether they support SMS interworking with the called network.
In other known solutions, call forwarding is normally available for missed calls from a fixed-line phone to a mobile phone. In prior art call forwarding from fixed-line phones to mobile phones, missed calls at the fixed-line phone are forwarded to a mobile phone. In such cases, the mobile phone user gets an incoming call if the fixed-line phone misses a call. This may not always be desirable to the user. The user may desire to receive only a notification or alert that a call has been missed at the fixed-line, without receiving the call on the mobile phone. Further, if the mobile phone misses the call too, the missed call alert received by the mobile phone is no different from the missed call alert it would receive if it were to miss a call that was originally routed for the mobile phone.
Despite these solutions for wireless mobile subscribers, there is no solution present today for fixed-line missed call alerts. That is, none of the state of the art solutions alerts a mobile subscriber when he misses a call to his fixed-line phone. There is a need in the art for a method to alert a mobile subscriber (or another subscriber whose telecommunications equipment is capable of displaying or conveying an alert message) when he has missed a call to his fixed phone line, or a telecommunications address other than his mobile handset.
Further, the missed call alerting solutions known in the art provide an alert only to the device that misses the call. However, when a user misses a call on a device, it is likely that the user will be unable to receive an alert of the missed call on the same device soon thereafter. Thus, there is a time lag between the time when a call is missed, and when the user gets alerted of the same. On the other hand, it is sometimes likely that a user who has missed a call on one device may be immediately available on another device.
Thus, there is a need for a solution that provides alerts to the user of a device about a call missed on that device in one network by using an alert sent through another device in another or same network.
The present invention discloses a simple and cost-effective solution for providing a user with an alert via his present phone handset, or any telecommunications address, when he has missed a call to a non-present phone handset, or any other telecommunications address.
In an embodiment, the present invention discloses a method of providing a Missed Call Alert (MCA) for a missed call to a first device in a first telecommunications network, wherein the MCA is provided to a second device in a second telecommunications network. The method comprises forwarding a call missed by the first device to a forwarding address in the second telecommunications network, and obtaining missed call details from the forwarded call at the second telecommunications network. The missed call details comprise the calling party address and the address of the first device. The method further comprises identifying the address of the second device, wherein the second device is associated with the first device, and alerting the second device of the missed call to the first device.
In another embodiment, the present invention discloses a method of providing a Missed Call Alert (MCA) for a missed call to a fixed-line phone, wherein the MCA is provided to a mobile phone. The method comprises forwarding a call missed by the fixed-line phone to a forwarding address in the mobile network, and obtaining missed call details from the forwarded call at the mobile network. The missed call details comprise the calling party address and the address of the fixed-line phone. The method further comprises identifying the address of the mobile phone, wherein the mobile phone is related to the fixed-line phone, and alerting the mobile phone of the missed call to the fixed-line phone.
In the drawings, the same or similar reference numbers identify similar elements or acts.
The present invention discloses a method of providing a Missed Call Alert (hereinafter MCA) for a call missed by a first device in a first telecommunications network, wherein the MCA is provided to a second device in a second telecommunications network. Various embodiments of the present invention teach a method of sending a missed call alert to a mobile phone line or first device, when a call is missed at a fixed-line phone or second device.
Then at step 104, the second telecommunications network obtains missed call details for the forward missed call, once it has been received on the forwarding address. The missed call details comprise the Calling Party Address (hereinafter CgPA), and the address of the first device (the Called Party Address, hereinafter CdPA). In various embodiments, further details about the missed call are obtained. The details may include, as a non-limiting example, the time of the missed call, and an indication that a voice mail message has been recorded in connection with the missed call. A number of techniques that may be employed by the second telecommunications network to obtain the missed call details are known in the art. Some of these techniques are discussed in this application by way of non-limiting example. It would be apparent to one skilled in the art that a variety of techniques to obtain the missed call details may be employed by the second telecommunications network without deviating from the spirit and scope of the present invention. Thereafter, at step 106, the second telecommunications network identifies a second device associated with the first device. The identified second device may be one that is used by the user of the first device. Various techniques for the identification of the second device are discussed in this application by way of non-limiting example. Various other techniques may be employed without deviating from the spirit and scope of the present invention.
Finally, at step 108, the second telecommunications network delivers an alert to the identified second device, notifying the second device of the missed call to the first device. The alert contains the missed call details, or at least a part thereof. In various embodiments, the missed call alert may be delivered to more than one device. For example, an MCA Short Message Service (SMS) message may be delivered to a second device. Additionally, an email message may be delivered. Further, alerts may be delivered selectively to the second device, based on the missed call details. Such selection may be, for example, according to the user's preference. In an embodiment, the user's preferences for selective delivery of MCAs are obtained from the user through a web-interface, and stored in a database in the second telecommunications network.
More specifically, the present invention finds an application in providing missed call alerts for fixed-line phones. It is often the case that the user of a fixed-line phone also uses a mobile phone. Further, it is often desirable in such cases to deliver a missed call alert for the fixed-line phone to the mobile phone of the user. Various embodiments of the present invention provide for delivery of missed call alerts for a user's fixed-line phone to the user's mobile phone.
In an embodiment, the forwarding address may be a universal forwarding address, to which missed calls to all fixed-line phones (that have subscribed for fixed-line MCA) are routed. In this case, call trunk 206 guarantees delivery of the missed calls details, or at least a part thereof, using ISUP/TUP. Further, fixed-line MCA logic 214 maintains relations database 216 that lists pre-defined relations between the fixed-line phones and mobile phones. In an embodiment, relations database 216 is compiled and maintained using a web-interface. In another embodiment, relations database 216 is compiled and maintained using SMS-based commands from the user's mobile phones.
In another embodiment, the forwarding address may be a user-specific forwarding address wherein a unique forwarding address is assigned for a user. The forwarding address, for example, can be a specially prefixed number that consists of a prefix that routes the missed call towards mobile network 204 and the user's mobile phone. In this case, there is no need to retrieve missed call details using call trunk 206. Furthermore, there is no need of relations database 216 to relate the fixed-line phone with the mobile phone.
Finally, mobile network 204 comprises a Short Message Service Center (SMSC) 218 to deliver MCA SMS alerts to the mobile phone (not shown in Figure).
Then at step 310, fixed-line MCA logic 214 issues a command to SMSC 218 to deliver a MCA SMS to the mobile phone. The command may be issued though an Internet Protocol (IP) link using, for example, Short Message Peer-to-peer Protocol (SMPP). Alternatively, the command may be issued via a Signaling System (SS7) link using, for example, Mobile Application Part (MAP). SMSC 218 then delivers the missed call alert as an SMS to the mobile phone. In various embodiments of the present invention, the alert may also be delivered to multiple mobile phones, email addresses, or both. The content of the alert indicates the calling party address, and the fixed-line phone address. The alert may optionally include additional information such as the time of the missed call and number of times that the same caller's calls were missed.
Then at step 312, fixed-line MCA logic 214 issues an ISUP Release (REL) command to mobile network switch 210, to release the call set up at step 308. At step 314, SMSC 218 acknowledges the delivery of the alert to the mobile phone. Finally, at step 316, mobile network switch 210 issues an ISUP REL command to fixed-line switch 208 to release the call set up at step 306. Therefore, the call is released without answering the call. The information from the call setup is used to obtain missed call information.
Subsequently, at step 508, the address of the mobile phone associated with the called user-specific forwarding address is obtained from relations database 216. Finally, at step 510, a missed call alert is delivered to the mobile phone, notifying of the call missed by the fixed-line phone. This approach may be implemented by the operator of mobile network 204 independent of the operator of fixed-line network. The user of the fixed-line phone only needs to subscribe to the call forwarding feature of fixed-line network 202 or just do a forwarding anytime on a need basis (hereinafter one-time need basis approach). The one-time need basis approach has the advantage that the user does not have to pay for the forwarded call since the forwarded call is never answered.
It would be apparent to one skilled in the art that the criteria used for identifying a call as a missed call is not a limitation on the application of the present invention. A call can be identified as a missed call, without limitation, in a “no answer” condition, a busy condition, or even unconditionally.
Provided above for the edification of those of ordinary skill in the art, and not as a limitation on the scope of the invention are detailed illustrations of a scheme for providing a Missed Call Alert (MCA) for a missed call to a first device in a first telecommunications network, wherein the MCA is provided to a second device in a second telecommunications network. Numerous variations and modifications within the spirit of the present invention will of course occur to those of ordinary skill in the art in view of the embodiments that have now been disclosed. For example, while in the described embodiments, the present invention is implemented primarily from the point of view of fixed-line missed call alerts, the present invention may also be effectively implemented for missed call alerts for mobile phone wherein the user wishes to be alerted of a call missed by another mobile phone or email client, or any other setup wherein missed call alerts are desired at devices (e.g. email clients) other than the device that missed the call.
The examples under the present invention, detailed in the illustrative examples contained here, are described using terms and constructs drawn largely from GSM mobile telephony infrastructure. But use of these examples should not be interpreted to limiting the invention to those media. The methods and principles disclosed by the present invention can be of use and provided through any type of telecommunications medium, including without limitation: (i) any mobile telephony network including without limitation GSM, 3GSM, 3G, CDMA, WCDMA or GPRS, satellite phones or other mobile telephone networks or systems; (ii) any so-called WiFi apparatus that is capable of receiving alert messages from a telecommunications network, including apparatus not dedicated to telecommunications such as personal computers, Palm-type or Windows Mobile devices; (iii) fixed-line devices capable of receiving alert messages such as the eye2eye devices from Dlink; or telecommunications equipment meant for voice over IP communications such as those provided by Vonage or Packet8.
In describing certain embodiments of the present invention, this specification follows the path of a telecommunications call from a calling party to a subscriber or called party. For the avoidance of doubt, that call can be for a normal voice call, in which the subscriber telecommunications equipment is also capable of visual, audiovisual or motion-picture display. Alternatively, those devices or calls can be for text, video, pictures or other communicated data.
